Your profitability is pegged against litecoin - Is it the most profitable single coin out there?
I did a quick compare to Doge here :
http://bitinfocharts.com/comparison/miningtobtc-ltc-doge.html because Doge was brought up earlier in discussion. Seems that as Doge seems to be a bit stronger than LiteCoin it may be a better benchmark for comparison.
I realize you can't cater to every coin, but perhaps put a couple other 'big' ones on there and it could help sell your site better?
Doge is a joke coin. Because of auto-switching pools raping the high-value blocks, the real profit from mining doge is much smaller then the projected income. Suffice to say, if you want to mine scrypt, you compare against the stable, highest hashrate, and non-retarded standard LTC.
Interesting, thanks for the perspective.
